Objective To explore the application value of multidetector computed tomography(MDCT),computed tomography cholangiography(CTC)and computed tomography angiography(CTA)reconstruction technology in the diagnosis and classification and the evaluation of the efficacy of biliary drainage in advanced hilar cholangiocarcinoma(HCCA).Methods A total of 44 patients of inoperable advanced HCCA were collected.Conventional CT plain scan and enhanced multi-phase scan were performed before treat-ment.Minimum intensity projection(MinIP)combined with curve planar reformation(CPR)was used to perform CTC.CTA of the portal vein,hepatic artery and hepatic vein were performed by maximum intensity projection(MIP),volume rendering(VR)or CPR,respectively.CT was reexamined after biliary drainage treatment.The study included the comparison between reconstruction technology of CTC and CTA and conventional CT scanning technology,CTC in the classification and diagnosis of HCCA,CTA in the evaluation of vascular invasion,and the evaluation of the effect of jaundice drainage by biliary imaging before and after biliary drain-age treatment.Results All HCCA cases obtained clear location diagnosis,including 39 cases of Bismuth-Corlette type Ⅳ and 5 cases of type Ⅲ.There were 40 cases of hepatic vascular involvement,including 15 cases of bilateral portal vein invasion by tumor,12 cases of portal vein constriction,8 cases of portal vein tumor thrombosis,4 cases of bilateral hepatic arteries involvement,and 1 case of hepatic vein involvement.CTC and CTA could better display a full view of the bile duct and blood vessel than conventional CT scanning ima-ges,and provided more accurate analysis of tumor classification and degree of vascular invasion.Before treatment,CT showed severe dila-tion of bile duct in 21 cases and moderate dilation in 20 cases,severe dilation of the intrahepatic bile duct in the left lobe but mild dilation of the intrahepatic bile duct in the right lobe in 3 cases.After drainage treatment,the contraction rate of intrahepatic bile duct dilation was＜25％in 4 cases,25％to 49％in 13 cases,50％to 74％in 18 cases,and ≥75％in 9 cases.The bile duct contraction rate was positively correlated with the decrease in total bilirubin(TBIL).Conclusion MDCT,CTC and CT A reconstruction technology can well complete the diagnosis of advanced HCCA,Bismuth-Corlette typing,and vascular evaluation.Observing the contraction rate of the intrahepatic bile duct after biliary drainage treatment can evaluate the efficacy of jaundice drainage.

Driven by multiple factors such as policy incentives,enhanced economic capacity of residents,aging popula-tion,and medical system reform,China's rehabilitation industry has been in a rapid development stage where opportunities and challenges coexist.Various rehabilitation hospitals urgently need new development thinking on how to seize the new opportunities for the development of rehabilitation medicine,give full play to the benefits of high-quality rehabilitation medical resources,and deal with the development of rehabilitation institutions under the new situation.Taking the tertiary rehabilitation hospital where the authors work as an example,this paper deeply analyzes the practical difficulties and challenges faced by the development of reha-bilitation hospital under the new circumstance,further explores the construction of a new working mode based on people-oriented and medical-rehabilitation integration.It also briefly summarizes the beneficial experiences and practices in the reform of rehabili-tation service models,and elaborates on the periodic achievement,so as to provide a meaningful reference for the majority of re-habilitation hospitals to plan and practice high-quality development and reform.

Objective:To investigate the efficacy and safety of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis.Methods:A retrospective analysis was carried out on 46 patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis who received endovascular treatment at the Strategic Support Force Medical Center from January 2015 to August 2022. Twenty-seven patients underwent balloon angioplasty alone and 19 patients underwent acute stent implantation. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of the responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality of the two groups were evaluated.Results:The proportion of effective recanalization of the offending vessels (mTICI≥2b) in the acute stenting group was slightly higher than that in the balloon angioplasty group (16/19 vs. 81.5%), but the difference was not statistically significant ( P>0.05). Besides, there was no significant difference in the median of mRS between the acute stenting group [3.0(0, 4.0)] and the balloon angioplasty group [4.0(1.0, 5.0)] 90 days after operation ( P>0.05). In terms of safety, the incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups ( P>0.05). Conclusions:The effect of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis is not inferior to that of balloon angioplasty, and it does not increase the risk of intracranial bleeding complications.

Wiskott-Aldrich syndrome (WAS) is a rare X-linked recessive genetic disorder characterized by thrombocytopenia, eczema, recurrent infections, and susceptibility to autoimmune diseases. The renal complication of WAS is mainly manifested as IgA nephropathy. Membranous nephropathy (MN) in children mostly has secondary factors, and its occurrence is related to immune disorders. This paper reports a case of WAS in an infant with bleeding tendency and recurrent infections, complicated with nephrotic syndrome during the course, confirmed as MN by pathological examination. After treatment with glucocorticoids, tacrolimus and hematopoietic stem cell transplantation, nephrotic syndrome was manifested as steroid-resistant and partially sensitive to tacrolimus. Proteinuria continued to relieve 3 months after hematopoietic stem cell transplantation and renal function remained stable. WAS complicated with MN is extremely rare, and its renal prognosis is still unclear, which deserves the attention of clinicians.

This case report described the sucussful treatment of a male infant born at 21 weeks and 4 days through assisted reproductive technology. After prenatal consultation and with the strong desire of the parents, active resuscitation and treatment were performed. The infant received 52 days of mechanical ventilation and was extubated to non-invasive ventilation at a corrected gestational age of 28 weeks and 6 days. During hospitalization, no vasoactive drugs were used, and necrotizing enterocolitis did not occur. The gastric tube was removed at a corrected gestational age of 37 weeks and 4 days. At a corrected gestational age of 40 weeks, cranial MRI showed no abnormalities. The infant was discharged at a corrected gestational age of 42 weeks after 143 days of treatment, without the need for any respiratory support. Follow-up until a corrected age of 6 months showed good growth and development.

Objective:To observe the impacts of using heated and humidified gas sources for delivery room resuscitation on the short-term outcomes of extremely preterm infants.Methods:A retrospective study was conducted on 231 extremely preterm infants admitted to the neonatal intensive care unit of Shenzhen Maternity & Child Healthcare Hospital, the First School of Clinical Medicine, Southern Medical University, from January 2020 to December 2022. The infants were divided into two groups based on whether heated and humidified gas sources were used during delivery room resuscitation: the heated and humidified group (103 cases) and the non-heated and humidified group (128 cases). Independent sample t-tests, Chi-square tests, and Mann-Whitney U tests were used to compare general conditions and short-term outcomes between the groups. Multivariate logistic regression analysis was used to assess the impact of using heated and humidified gas sources during delivery room resuscitation on the short-term outcomes of extremely preterm infants. Results:Compared to the non-heated and humidified group, the heated and humidified group had a lower incidence of intubation resuscitation [28.2% (29/103) vs. 41.4% (53/128), χ 2=4.38], moderate to severe bronchopulmonary dysplasia (BPD)/death [22.3% (23/103) vs. 39.1% (50/128), χ 2=7.39] and low rectal temperature upon admission (<36.7 ℃) [57.3% (59/103) vs. 79.7% (102/128), χ 2=13.57], while the rectal temperature upon admission was higher [36.3 ℃ (36.0-36.7 ℃) vs. 35.9 ℃ (35.5-36.3 ℃), U=－5.05], with all differences being statistically significant (all P<0.05). After adjusting for gender, gestational age, mode of delivery, amniotic fluid condition, weight on admission, maternal premature rupture of membranes, assisted reproductive technology, and full course of prenatal steroid use, multivariate logistic regression analysis showed that the use of heated and humidified gas sources during delivery room resuscitation could increase the hospital admission rectal temperature ( β=0.46, 95% CI: 0.28-0.64), and decrease the risks of severe BPD/death ( aOR=0.39, 95% CI: 0.20-0.75), and low rectal temperature upon admission ( aOR=0.29, 95% CI: 0.16-0.55)(all P<0.05). Compared to the non-heated and humidified group, the heated and humidified group showed no statistically significant differences in the use of pulmonary surfactant [37.9% (39/103) vs. 43.8% (56/128), χ 2=1.45], incidence of stage Ⅲ or higher necrotizing enterocolitis [2.0% (2/103) vs. 5.5% (7/128), χ 2=2.06], grade Ⅲ or higher intracranial hemorrhage [2.9% (3/103) vs. 3.9% (5/128), χ 2=0.22], and retinopathy of prematurity requiring surgical treatment [3.9% (4/103) vs. 10.2% (13/128), χ 2=3.60] (all P>0.05). Conclusion:The use of heated and humidified gas sources during resuscitation of extremely preterm infants can reduce the risk of moderate to severe BPD/death, help maintain warmth during resuscitation, and do not adversely affect other short-term outcomes.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Immune imbalance is believed to play a dominant role in the pathogenesis of chronic urticaria.While Th1/Th2 imbalance used to be considered as the main contributing factor of the development of chronic urticaria.Recently,Th17/Treg imbalance is found to be an important immune mechanism leading to the development of chronic urticaria.To be more specific,according to traditional Chinese medicine(TCM)'s comprehensive understanding of the etiology of chronic urticaria.it is generally believed that the pathogenesis of chronic urticaria is due to a lack of innate endowment,a lack of solidity of the body surface,and repeated exposure to six pathogenic factors.Another possible reason lies with dietary disorders that generate heat and wind or chronic illness and weakness and loss of nourishment of qi and blood.Therefore,in terms of the treatment,from the perspective of sthenia syndrome,it is advisable to remove the wind and disperse the pathogenic factors and clear the dampness and heat.From the perspective of asthenia syndrome,it is advisable to nourish the qi and blood and support the righteousness.As for mixed excess and deficiency,both support the healthy atmosphere and dispel the pathogenic factors are important.Regarding the effects of TCM on the balance of Th17/Treg in chronic urticaria and immune diseases,it mainly involved herbal compounding,herbal active ingredients and single herbs.However,the research attention has been drawn to investigating the role of TCM in the treatment of chronic urticaria and various immune diseases based on the research outcomes in modern pharmacological research.This can not only provide scientific evidence for TCM treatment of chronic urticaria,but also bring benefits to more patients with immune diseases.Therefore,the author reviews the recent research progress of TCM on the effects of Th17/Treg immune imbalance in chronic urticaria and other immune diseases by explaining the effects of Th17 and Treg cells in chronic urticaria.

OBJECTIVE Cognitive deficit is a com-mon comorbidity in temporal lobe epilepsy(TLE)and that is not well controlled by current therapeutics.Currently,how epileptic seizure affects cognitive performance remains largely unclear.The subiculum is the major out-put of the hippocampus,which projects to entorhinal cor-tex and other more distinct brain regions.Physiologically,the subiculum codes spatial working memory and naviga-tion information including place,speed,and trajectory.Importantly,prior studies have noted the importance of the subiculum in the beginning,spreading,and generaliz-ing process of hippocampal seizure.How seizure-activated neurons in subiculum participate in cognitive impairment remains largely elusive.METHODS In this study,we sought to label the subicular seizure-activated c-fos+ neu-rons with a special promoter with enhanced synaptic activity-responsive element E-SARE in the subiculum,combined with chemogenetics and designer receptors exclusively activated by designer drugs(DREADDs),Ca2+ fiber photometry approaches,and behavioral tasks,to reveal the role of these neurons in cognitive impairment in epilepsy.RESULTS We found that chemogenetic inhibi-tion of subicular seizure-tagged c-fos+ neurons(mainly CaMK Ⅱ α+ glutamatergic neurons)alleviates seizure generalization and improves cognitive performance in the hippocampal CA3 kindling TLE model.While inhibition of seizure-labeled c-fos+ GABAergic interneuron shows no effect on seizure and cognition.As a comparison,che-mogenetic inhibition of the whole subicular CaMK Ⅱ α+ neuron impairs cognitive function in na?ve mice in basal condition.Notably,inhibition of subicular seizure-tagged c-fos+ neurons enhances the recruitment of cognition-responsive c-fos+ neurons via increasing neural excitability during cognition tasks.CONCLUSION Our results dem-onstrate that subicular seizure-activated c-fos+ neurons contribute to cognitive impairment in TLE,suggesting sei-zure-tagged c-fos+ neurons as the potential therapeutic target to alleviate cognitive impairment in TLE.

OBJECTIVE: To analyze the clinical features and genotype of a child with Schmid type metaphyseal chondrodysplasia. METHODS: Clinical data of the child and her parents was collected. The child was subjected to high-throughput sequencing, and candidate variant was verified by Sanger sequencing of her family members. RESULTS: Whole exome sequencing revealed that the child has harbored a heterozygous c.1772G>A (p.C591Y) variant of the COL10A1 gene, which was not found in either of her parents. The variant was not found in the HGMD and ClinVar databases, and was rated as likely pathogenic based on the guidelines from the American College of Medical Genetics and Genomics (ACMG). CONCLUSION The heterozygous c.1772G>A (p.C591Y) variant of the COL10A1 gene probably underlay the Schmid type metaphyseal chondrodysplasia in this child. Genetic testing has facilitated the diagnosis and provided a basis for genetic counselling and prenatal diagnosis for this family. Above finding has also enriched the mutational spectrum of the COL10A1 gene.
